The C.A.T. Pixel Proportional Gas Counter Detector
نویسندگان
چکیده
A simple geometry of real pixel gas detectors has been evaluated that circumvents the limitations of a microstrips, namely aging, gain drift and flux limitation due to the dielectric charging. A good resolution has been obtained while preserving a large active size and a high gain and counting rate capabilities.

آشکارسازی پرتوهای آلفا با استفاده از کارکرد آشکارسازهای گازی مقیاس ریز در مد SQS
In gas detectors with UV absorbing gas mixture, the Self-Quenched Streamer (SQS) mode can be achieved following the proportional mode, which leads to appear the light column. In this study, the design, simulation and construction of three micro pattern gas-detector, THGEM, with different geometric dimensions are presented. Moreover, the ability of operation in SQS mode to determine incident ray...
متن کاملThe gas proportional scintillation counter / microstrip gas chamber hybrid detector
The gas proportional scintillation counter/microstrip gas chamber (GPSC/MSGC) hybrid detector for X-ray spectrometry is described. The detector uses a CsI-coated microstrip plate placed in direct contact with the gas-filling as the photosensor readout for the GPSC scintillation substituting for the photomultiplier tube (PMT). Usable photosensor maximum gain is limited by optical positive feedba...
متن کاملCharacterization of a mid-sized Li foil multi-wire proportional counter neutron detector
A 550 cm thermal neutron detector was constructed with five parallel sheets of 75 mm thick Li foil (95% enrichment) spaced 1.63 cm apart. Anode wire banks containing a plurality of anode wires were strung on both sides of each foil, six banks in total. The chamber was backfilled with P-10 proportional gas and over-pressured to 1.1, 1.5, 2.0, and 2.8 atm (111, 151, 202, and 284 kPa). The design ...

A scintillation proportional counter with wavelength shifting fiber readout filled with Xe or Kr under a pressure of up to 20 atm is proposed for the low–background experiments on search for dark matter of the Universe and 2K–decay of Kr.
متن کاملCalibrating SANS data for instrument geometry and pixel sensitivity effects: access to an extended Q range
An improved data-reduction procedure is proposed and demonstrated for small-angle neutron scattering (SANS) measurements. Its main feature is the correction of geometry- and wavelength-dependent intensity variations on the detector in a separate step from the different pixel sensitivities: the geometric and wavelength effects can be corrected analytically, while pixel sensitivities have to be c...
